In our current environment the key challenges for Management Information Systems are in coping with new technologies, (performance) Management, and organizing IT Systems. Due to the rapid and somewhat forced virtualization of all enterprises these are almost identical to General Management Challenges. The question arises if there is a substantial difference between General and IS Management at the moment and also in the future. --- ## Globalization Challenges and Opportunities: A Flattened World Internet and global communications have greatly reduced economic and cultural advantages of developed countries. - Drastic reduction of costs of operating and transacting on global scale - Competition for jobs, markets, resources, ideas - Dependence on imports and exports - Requires new understandings of skills, markets, opportunities --- class: list-overview ## Business Drivers of Information Systems Businesses invest in IT to achieve six important business objectives. - Operational excellence - New products, services, and business models - Customer and supplier intimacy - Improved decision making - Competitive advantage - Survival --- ## Operational Excellence * Improved efficiency results in higher profits. * Information systems and technologies help improve efficiency and productivity. * Example: Walmart * Power of combining information systems and best business practices to achieve operational efficiency—and over $514 billion in sales in 2019 * Most efficient retail store in world as result of digital links between suppliers and stores --- ## New Products, Services, and Business Models <!-- TODO Apple Business Model --> ??? * Information systems and technologies enable firms to create new products, services, and business models. * Business model: how a company produces, delivers, and sells its products and services * Example: Apple * Transformed old model of music distribution with iTunes * Constant innovations—iPod,iPhone,iPad, etc. --- ## Customer and Supplier Intimacy * Customers who are served well become repeat customers who purchase more. * Mandarin Oriental Hotel uses IT to foster an intimate relationship with its customers, keeping track of preferences, and so on * Close relationships with suppliers result in lower costs. * JCPenney * IT to enhance relationship with supplier in Hong Kong --- ## Improved Decision Making If managers rely on forecasts, best guesses, and luck, they will misallocate employees, services, and inventory. Real-time data improves ability of managers to make decisions. Verizon: web-based digital dashboard to update managers with real-time data on customer complaints, network performance, and line outages --- ## Competitive Advantage * Often results from achieving previous business objectives * Advantages over competitors: * Charging less for superior products, better performance, and better response to suppliers and customers * Examples: Apple, Walmart, andU P Sare industry leaders because they know how to use information systems for this purpose --- ## Survival * Businesses may need to invest in information systems out of necessity; it is simply the cost of doing business. * Keeping up with competitors * Citibank’s introduction ofA T Ms * Federal and state regulations and reporting requirements * Toxic Substances Control Act and the Sarbanes-Oxley Act --- # What Is an Information System? * Information technology: the hardware and software a business uses to achieve objectives * Information system: interrelated components that manage information to: * Support decision making and control * Help with analysis, visualization, and product creation * Data: streams of raw facts * Information: data shaped into meaningful, useful form * Activities in an information system that produce information: * Input * Processing * Output * Feedback * Sharp distinction between __computer__ or __computer program__ versus __information system__ --- ## Figure 1.1 Data and Information {height=80%, width=80%} --- ## Figure 1.2 Functions of an Information System {height=80%, width=80%} --- ## The Role of People and Organizations * Information systems literacy * Includes behavioral and technical approach * Computer literacy * Focuses mostly on knowledge ofI T * Management information systems (M I S) * Focuses on broader information systems literacy * Issues surrounding development, use, impact of information systems used by managers and employees * Focuses on firm performance, productivity, and competitive challenges --- ## Figure 1.3 Information Systems Are More Than Computers {height=80%, width=80%} --- ## Dimensions of Information Systems .fl.w-third[ ### Organizations - Coordinate work through structured hierarchy and business processes - Business processes: related tasks and behaviors for accomplishing work ] .fl.w-third[ ### People - Information systems require skilled people to build, maintain, and use them. - Employee attitudes affect their ability to use systems productively. ] .fl.w-third[ ### Technology * IT Infrastructure: Foundation or platform that information systems are built on * Computer hardware * Computer software * Data management technology * Networking and telecommunications technology ] --- ## CRITICAL THINKING: <br \> In the Digital Age, do these statements hold true? ### Statement on Organizational Structure > Coordinate work through structured hierarchy and business processes ### Statement on Management > Role of managers: - Perceive business challenges - Set organizational strategy - Allocate human and financial resources - Creative work: new products, service --- ## Interactive Session – Technology: US Competes Globally with Information Technology * Class discussion * What are the inputs, processing, and outputs of UPS’s package tracking system? * What technologies are used by UPS? How are these technologies related to UPS’s business strategy? * What strategic business objectives do UPS’ sinformation systems address? * What would happen if UPS’ sinformation systems were not available? --- # A Problem-solving Mindset * Few business problems are simple or straightforward. * Most business problems involve a number of major factors that can fall into three main categories: * Organization * Technology * People --- ## A Model of the Problem-Solving Approach Problem solving: four-step process * Problem identification * Solution design * Choice * Implementation --- ## Problem identification includes: * Agreement that problem exists * Definition of problem * Causes of problem * What can be done given resources of firm --- ## Typical organizational problems * Outdated business processes * Unsupportive culture and attitudes * Political in-fighting * Turbulent business environment, change * Complexity of task * Inadequate resources --- ## Typical technology problems * Insufficient or aging hardware * Outdated software * Inadequate database capacity * Insufficient telecommunications capacity * Incompatibility of old systems with new technology * Rapid technological change --- ## Typical people problems * Lack of employee training * Difficulties of evaluating performance * Legal and regulatory compliance * Work environment, ergonomics * Poor or indecisive management * Lack of employee support and participation --- ## Solution design * Often many possible solutions * Consider as many as possible to understand range of solutions --- ## Solution Evaluation and Choice – factors include: * Cost * Feasibility given resources and skills * Length of time needed to implement solution --- ## Implementation * Building or purchasing solution * Testing solution, employee training * Change management * Measurement of outcomes * Feedback, evaluation of solution * Problem solving is a continuous process, not a single event * Sometimes chosen solution doesn’t work or needs adjustment --- ## Figure 1.4 Problem Solving Is a Continuous Four-Step Process {height=80%, width=80%} --- ## The Role of Critical Thinking in Problem Solving (1 of 2) * Without critical thinking, easy to jump to conclusions, misjudge a problem, and waste resources * Critical thinking: * Sustained suspension of judgment with an awareness of multiple perspectives and alternatives * Ability to collect and analyze data that might help understand the nature of the problem; a “data driven” approach * Four elements of critical thinking: * Maintaining doubt and suspending judgment * Being aware of different perspectives * Including technology, organization, and people perspectives * Testing alternatives and letting experience guide * Being aware of organizational and personal limitations --- ## The Connections Among Business Objectives, Problems, and Solutions When firms cannot achieve business objectives these objectives become challenges. Information systems often present solutions, partially or fully, to these challenges. --- ## How Information Systems Will Affect Business Careers - Success in today’s job market requires a broad set of skills. - Job candidates must have problem-solving skills as well as technical skills so that they can complete specific tasks. - The service sector will account for 95 percent of the new jobs that are created or open up by 2022. .panelset[ .panel[.panel-name[Accounting] Accountants increasingly rely on information systems to summarize transactions, create financial records, organize data, and perform financial analysis.

Walmart * Inventory replenishment system sends orders to suppliers when purchase recorded at cash register * Minimizes inventory at warehouses, operating costs * Efficient customer response system ] .panel[.panel-name[Product differentiation] * Use information systems to enable new products and services, or greatly change the customer convenience in using your existing products and services * E.g., Google's continuous innovations, Apple's iPhone * Use information systems to customize, personalize products to fit specifications of individual consumers * E.g., Nike's NIKEi Dprogram for customized sneakers ] .panel[.panel-name[Focus on market niche] * Use information systems to enable specific market focus, and serve narrow target market better than competitors. * Analyzes customer buying habits, preferences * Advertising pitches to smaller and smaller target markets E.g., Hilton Hotel’s OnQSystem * Analyzes data collected on guests to determine preferences and guest's profitability ] .panel[.panel-name[Strengthen customer and supplier intimacy] * Strong linkages to customers and suppliers increase switching costs and loyalty * Toyota: usesI Sto facilitate direct access from suppliers to production schedules * Permits suppliers to decide how and when to ship supplies to plants, allowing more lead time in producing goods * Amazon: keeps track of user preferences for purchases, and recommends titles purchased by others ] ] --- ## The Internet’s Impact on Competitive Advantage - Enables new products and services - Encourages substitute products - Lowers barrier to entry - Changes balance of power of customers and suppliers - Transforms some industries - Creates new opportunities for creating new markets, building brands, and large customer bases - Smart products and the Internet of Things --- class: segue-red # Value Chain --- ## The Business Value Chain Model * Highlights specific activities in a business where competitive strategies can best be applied and where information systems are likely to have a strategic impact. * Primary activities * Support activities * Benchmarking * Best practices --- Figure 3.2 The Value Chain Model -------- <img src="data:image/png;base64,#img/laudon_emis14_ppt_ch03_MS-ct2.jpg" width=500px /> --- ## The Value Web * A firm’s value chain is linked to the value chains of its suppliers, distributors, and customers. * Value web * Collection of independent firms that use information technology to coordinate their value chains to produce a product collectively * Value webs are flexible and adapt to changes in supply and demand --- ## Figure 3.3 The Value Web <img src="data:image/png;base64,#img/laudon_emis14_ppt_ch03_MS-ct3.jpg" width=500px /> --- class: segue-red # Synergies, Core Competencies, and Network-Based Strategies * Large corporations comprised of business units * Financial returns overall are tied to performance of business units * Information systems improve performance of business units by promoting * Communication * Synergies (Revenue, Cost, Financial) * Core competencies, Dynamic Capabilities --- ## Synergies ### Types of Synergies - Revenue - Cost - Financial ### Examples - When output of some business units can be used as inputs to other units - When two firms can pool markets and expertise (e.g., recent bank mergers) to lower costs and generate profits - Enabled by information systems that ties together disparate units so they act as whole ??? --- ## Core Competency * Activities for which firm is world-class leader * E.g., world’s best miniature parts designer, best package delivery service, etc * Relies on knowledge gained over years of experience as well as knowledge research * Any information system that encourages the sharing of knowledge across business units enhances competency * E.g., Procter & Gamble uses intranet to help people working on similar problems share ideas and expertise. --- ## Network-Based Strategies * Network economics * Marginal costs of adding another participant are near zero, whereas marginal gain is much larger * E.g., larger number of participants in Internet, greater value to all participants * Virtual company * Uses networks to link people, resources, and ally with other companies to create and distribute products without traditional organizational boundaries or physical locations --- ## Disruptive Technologies * Technologies with disruptive impact on industries and businesses, rendering existing products, services and business models obsolete * Personal computers * World Wide Web * Internet music services * First movers versus fast followers * First movers of disruptive technologies may fail to see potential, allowing second movers to reap rewards (fast followers) --- ## The Internet and Globalization * Prior to the Internet, competing globally was only an option for huge firms able to afford factories, warehouses, and distribution centers abroad. * The Internet drastically reduces costs of operating globally. * Globalization benefits * Scale economies and resource cost reduction * Higher utilization rates, fixed capital costs, and lower cost per unit of production * Speeding time to market --- ## Figure 3.4 Apple i Phone’s Global Supply Chain <img src="data:image/png;base64,#img/laudon_emis14_ppt_ch03_MS-ct4.jpg" width=500px /> --- ## Global Business and System Strategies Domestic exporters Multinationals Franchisers Transnationals --- ## Global System Configuration Centralized systems Duplicated systems Decentralized systems Networked systems --- ## Figure 3.5 Global Business Organization Systems Configurations <img src="data:image/png;base64,#img/laudon_emis14_ppt_ch03_MS-ct5.jpg" width=500px /> --- class: segue-red # Quality and Business Processes --- ## What is Quality?
